DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to the drawings.
The embodiment has both a panic prevention and a non- keyless locking mechanism . FIG. 1 shows a locked state in a door closed state, FIG. 2 shows a panic occurrence state, FIG. 3 shows a panic released state, and FIG.
And FIG. 5 show a non- keyless lock state.
, A striker attached to the vehicle body; and 2, a latch of a latch device attached to the door. The latch 2 is mounted on a shaft 3, and when the door is closed on the outer peripheral surface, an engagement groove 4 with which the striker 1 is engaged, a half-latch engagement step 7 with which the pawl 6 of the ratchet 5 is engaged, and a full-latch engagement step Part 8
Are provided so as to be recessed in the radial direction. Reference numeral 9 denotes a lock lever mounted on the shaft 3, and a gear portion 11 is formed at the upper end of a vertical piece 10 of the lock lever so as to engage with a motor gear, so that lock / unlock can be switched electrically by a motor.
The first horizontal piece 12 of the lock lever 9 is provided with a rod connecting hole 13 reaching the sill knob, and the second horizontal piece 14 is provided with a rod (not shown) reaching the key cylinder and an upper end of a link 15 extending downward. The shaft is fixed on the shaft 16. At the lower end of the link 15, a panic prevention piece 18 is axially fixed by a shaft 17. The panic prevention piece 18 is fixed to the link 15 in a horizontal direction (FIG.
From 1), it is pivoted downward as shown in FIG. 2, and the contact surface 19 on the link 15 side and the contact surface 20 on the panic prevention piece 18 contact and fix in the horizontal direction.

[0006] The spring 21 is attached to the shaft 17, spring 21 links the contact surface 20 of the panic preventing piece 18 at all times
15 to a position where it comes into contact with the contact surface 19 . At the tip side surface of the panic prevention piece 18, an engaging pin 2 bulging at a right angle is provided.
2 are provided. The engagement pin 22 may be made of resin integral with the panic prevention piece 18 or made of metal such as a pin. The engagement pin 22 engages with the long hole 24 of the open lever 23 and moves up and down in the long hole 24. The open lever 23 is mounted on a shaft 25 of the ratchet 5, and a ratchet lever 26 is also mounted on the shaft 25. The ratchet lever 26 is made of resin, extends in the same direction as the ratchet 5, and has a tip connected to the ratchet 5 by a connecting pin 27. When the ratchet lever 26 rotates, the ratchet 5 rotates via the connecting pin 27. .

[0007] The ratchet lever 26, the engaging recesses 28 to be engaged is provided when the engaging pin 22 moves upward. In the engagement recess 28, the entrance 29 is narrow and the back is widened to form the escape portion 30. One escape portion wall 33 is provided outside the escape portion 30, and the other wall of the entrance 29 has a wall 31 . A contact wall 32 is provided near the entrance 29 of the engagement recess 28. The relationship between the engagement pin 22, the engagement recess 28, and the contact wall 32 is that the pawl 6 of the ratchet 5 is disengaged from the half-latch engagement step 7 or the full-latch engagement step 8. in the state, as shown in FIG. 4, the door opening hand
Even if the open lever 23 is turned to the right by the door opening operation and the pawl 6 of the ratchet 5 is separated from the latch 2, even if the pawl 6 of the ratchet 5 is in contact with the latch 2 as shown in FIG. A relief wall 33 and a contact wall 3 are provided outside the engagement pin 22.
2, the engaging pin 22 is formed so as not to come off from the engaging recess 28.

[0008]

Next, the operation will be described. When the door is closed, the striker 1 on the vehicle body side engages with the engagement groove 4 of the latch 2 on the door side, the latch 2 is turned to the left in the drawing, and the pawl 6 of the ratchet 5 engages with the full latch engagement step 8 of the latch 2. Fully latched together. Then, the motor or, when rotating the lock lever 9 by a key or Shirunobu operated lock position, the link 15 moves downward, the lower end of the panic preventing piece 18 of the link 15 is also moved downward,
The engagement pin 22 of the panic prevention piece 18 comes out of the entrance 29 of the engagement concave portion 28 of the ratchet lever 26, moves down the long hole 24 of the open lever 23, and enters the locked state of FIG.
In the state shown in FIG. 1, even if the open lever 23 is rotated to move the engaging pin 22 to the left by the elongated hole 24, the ratchet lever 26 does not rotate because the ratchet lever 26 does not rotate because the ratchet lever 26 does not rotate. The door cannot be opened without being disengaged from the full-latch engagement step 8 and kept engaged.

However, in FIG. 1, when the lock lever 9 is turned to the left by operating a sill knob or a key and the shaft 16 is brought to the unlock position, the link 15 moves upward, the panic prevention piece 18 also moves upward, and the engaging pin When the open lever 23 is turned to the right , the engaging pin 22 is moved to the wall of the ratchet lever 26 because the engaging pin 22 is engaged with the engaging recess 28 through the inlet 29.
The ratchet lever 26 is turned to the right via the engaging pin 22 while contacting the ratchet 31, and the ratchet 5 is turned to the right via the connecting pin 27 to disengage the pawl 6 from the full-latch engaging step 8 and open the door.

At this time, the timing is bad, and
If the unlocking operation is performed simultaneously with the door opening operation from the outside of the vehicle, the conventionally known door cannot be opened due to panic. And can not be the door opening in panic, usually known ones, after the lock operation, once unlock
Although the door cannot be opened without operating the outer door opening handle and then opening the outer door opening handle, in the embodiment of the present application, the door can be opened only by re-opening the outer door opening handle.

That is, when the lock lever 9 is rotated to the unlock position, the shaft 16 of the link 15 moves upward to the unlock position accordingly. At this time, the opening lever 23 is simultaneously opened by the opening operation of the open lever 23. Long hole 24
Wall 31 off from the inlet 29 of the engagement recess 28 as through engagement pin 22 is 2 to MadeSusumu Mukara, panic preventing piece 18
The engagement pin 22 collides with the wall 31 of the entrance 29 and is simply opened , and the lock lever 9 can rotate to the unlock position .

The ratchet lever 26 is provided with an engaging recess 28 which engages when the engaging pin 22 moves upward, and a contact wall 32 is provided near the inlet 29 so that the engaging pin 22 in the engaging said the engagement recess 28 relationship abutment wall 32, the door opening state pawl 6 of the ratchet 5 is deviated from the half-latch engagement Godan unit 7 or the full-latch engagement Godan portion 8 and, FIG. 4 Opening operation of the opening handle like
Also pawl 6 of the ratchet 5 open lever 2 3 Right rolling with work is away from the latch 2, even if the pawl 6 of the ratchet 5 as shown in FIG. 5 is not in contact with the latch 2, the engagement
The escape wall 33 and the abutment wall 32 are located outside the mating pin 22 , and the engaging pin 22 is formed so as not to be disengaged from the engaging concave part 28. Locking is not possible, so it is possible to prevent the key from being left in the car.
